Thanks for this - but my version of PV Master tells me the same thing and then lists my inverters

I have been backwards and forwards with GoodWe support and they have never suggested to try SolarGo - will download it now and see what it says.

Interestingly enough - i have now converted one of my inverters back to WIFI and i can see difference in the main screen - it is fairly obvious whoever wrote it never contemplated someone using 3 of these with LAN adapter.

When i have the LAN adapters in installed - the initial screen lists 3 devices as HF_E20 - no other identifiers - you have to select one and go to the next screen to see which is which and if you pick the wrong one - you go back to the main window and start again - however if you have the WIFI dongles it lists then as Solar-WiFi and then part of the serial number of the inverter so you can differentiate from the main screen - just poor UX design

Yeah just tried SolarGo and it cam back with can not find any supported inverters - pretty sure it is meant for inverters with PV capability whereas mine are AC Coupled only.

My first post here.  Thank you for a great forum.

I had a system installed 2 days ago.  Goodwe GW5048D-ES, 2 x Pylontech 3.5kWh batteries and 6 panels totalling 2kW.

Everything seems to be working fine, but the installer was reluctant giving me control to change my settings myself - Only the SEMS Portal.

He made a mistake and set my battery to 30% DOD max (on grid), which makes the system not very efficient.

The company I bough from told me to use PV Master to change settings, but I struggle for hours to get it to connect to my system.

SEMS Portal connects no problem (WiFi connected to home WiFi router.  I found EZManage which also connects no problem, and I can get into the setup, but for some or other reason I cannot set the DOD % and it also dont have the Pylontech 3000, only Pylontech 2000B in the setup.

I somehow managed to get  the PV Master to connect last night and changed the percentages, but tonight it is the same story:  No connection.

Any ideas how I can get it to connect more reliably or something else I can use to play around with the settings?

Thank you in advance 

How many wifi routers do you have in your house? To use PV master you must be connected to the same wifi node as the inverter uses to talk to SEMS, or you must connect directly to the inverter itself.
 

Has anyone worked out how to turn off the SSID/AP broadcast from the WIFI dongles once they are connected to your home WIFI ? I would prefer not to have AP broadcasts like that for security reasons.

Thanks. 

I am based in Centurion. 

At the moment i cannot access the PV master and inverter shows offline on SEMS. I cannot make any changes to settings nor can i view data.

 

 

Hi Rehaan

Did you manage to get your system sorted out? I did a DIY installation of my Goodwe and PV panels and learned a lot in the process.

I am basically doing the same and it is working perfectly. I have an old (serial number starts with a 3) ES inverter and Pylontech batteries. The old inverters can not communicate directly with the Pylontechs (without an expensive external EZConverter). I have set the appropriate battery parameters using "battery self define" and it works so well that I never bothered to establish the communication between inverter and batteries . I remember that @Bobster had a similar problem with his Revov's. Maybe he can advice why the "battery self define"  route also never worked for him and why. Before you change to a Victron make sure that it can communicate with your batteries.

Hi

 

Could you share the settings you used for the battery self define?

 

Thanks

ECONOMICAL MODE SETTINGS GoodWe Solar Go App

A while ago a posted information on the Economical Mode Settings as it is quite hard to understand what it means. I thought to post an update as my old post was quite confusing itself. Economical mode is quite useful when you have a battery and also time-of-use charges or meter power charges which vary at certain times (i.e higher at peak times).

Some things to note: In the Economical Mode settings of the GoodWe Solar Go App you can set up to 4 different time schedules for solar (PV) system, and you can also select certain days of the week. These schedules cannot overlap past midnight. There are two choices (battery) Charge or Discharge, as well as a Rated Power option, which corresponds to rated power of your inverter (i.e 10% of a 5,000W system = 500W). Charge and 0% is not selectable. While if nothing is selected for a chosen time it defaults to operating the same as Discharge and 0% rated power. Solar panels = PV

Here's the info:

• GRID: Select Charge with 1% to supply all load with Grid Power. Battery does not discharge. PV charges battery first, reduces load second, then exports to grid third. Useful for off-peak when time-of-use tariffs are lower.
• SOLAR PV (and BATTERY): No need to select anything to supply all load with PV. PV excess charges battery first, and exports to grid second. Battery discharges to cover load shortfall to the set State of Charge (SOC). Grid covers shortfall if battery empty. Useful for during the day and peak times.
• SOLAR PV (and GRID): Select Discharge with 1% to supply all load with PV. PV excess is exported to grid (does not charge battery). Battery discharges at 1% of the rated power (i.e 50W for a 5000W inverter) to cover the load first, and export to the grid second to the minimum State of Charge. Grid covers the remainder of the shortfall or if the battery is empty. Useful for holding the battery charge (as best as possible given the limitations of the app). Useful for off-peak times falling during daylight hours, where preference is given to using Grid power to cover a shortfall, rather than the battery.
• GRID (+ GRID BATTERY RECHARGE): Select Charge with 2% or greater Rated Power to supply all load with Grid Power. Battery is charged from the Grid up to the set rated power (i.e 10% = 500W for a 5,000W inverter). PV charges battery first, reduces load second, then exports to grid third. Useful for if there is a very low off-peak tariff (note that there wear and tear and other costs may be incurred by using your battery, and often it is better to simply use Grid power directly if required rather than using it to charge the battery), for a few hours in advance of a very high peak tariff (to ensure a battery is topped up on rainy days) or other reasons (such as unstable power).
• SOLAR PV (+ BATTERY EXPORT TO GRID): Select Discharge with 2% or greater to supply all load with PV. PV excess is exported to grid (does not charge battery). Battery discharges at the set rated power (i.e 20% = 1,000W for a 5000W inverter) to cover the load first, and export to the grid second to the minimum State of Charge. Grid covers the remainder of the shortfall or if the battery is empty. Not recommended as there are costs involved with using your battery, including wear and tear on the battery life, unless there are very high energy export rebates, or in other special situations.
